After studying the material of this chapter, the student should be able to:
1. Use the wave model to explain reflection of light from mirrors and refraction of light as it passes from one medium into another.
2. Use the conditions for constructive and destructive interference of waves to explain the interference patterns observed in the Young's double slit experiment, single slit diffraction, diffraction grating, and thin film interference.
3. Solve problems involving a single slit, a double slit and a diffraction grating for m, λ, d, D, and angular separation (θ), when the other quantities are given.
4. Solve problems involving thin film interference for m, λ, n, or t when the other quantities are given.
5. Explain how the Michelson interferometer can be used to determine the wavelength of a monochromatic light source and solve problems to determine the wavelength of the light from the source.
6. Use the wave model to explain plane polarization of light, polarization by reflection, and polarization by double refraction.
7. Calculate the angle of maximum polarization for reflected light.
